[recipes] Simplify an API

[Matthias Clasen <matthiasc src gnome org>]

commit 4aa238cc26ce08978eb7c1d55e62b5ff86175cf8
Author: Matthias Clasen <mclasen redhat com>

    Simplify an API
    
    gr_window_show_diet does not need a separate title
    argument, since we can find the title from the diet.
    
    Update all callers.
